5.1.10 vl_target_velocity (Index: 6042h)
The vl target velocity is the required velocity of the system. It is multiplied the vl dimension factor
and the vl set-point factor, if these are implemented.
Inverter parameter = output frequency setting (Multi-speed0) (A020)

(unit: min Minimum unit: 1dig= 1min
5.1.11 vl_velocity_demand (Index: 6043h)
The vl velocity demand is the instantaneous velocity provided by ramp function, scaled to the unit of
the vl target velocity.
Inverter parameter = output frequency monitor (d001)

(unit: min Minimum unit: 1dig= 1min
5.1.12 vl_velocity_effort (Index: 6044h)
The vl velocity effort is the velocity at the motor spindle or load, scaled to the unit of the vl target
velocity.
-1
(unit: min Minimum unit: 1dig= 1min
5.1.13 vl_velocity_min_max_amount (Index: 6046h)
The vl velocity min-max amount index is composed of the vl velocity min(Sub-index1) amount and vl
velocity max(sub-index2) amount sub-index. (32bit length)
Sub-index1 = 1st frequency minimum limiter (A062)
Sub-index2 = 1st frequency maximum limiter (A061)
